Inventor: SONG JEONG-GON
IPC: G05D1/02
Filed: 2002-04-16
Abstract: A robot cleaner capable of returning to an external recharging device. The robot cleaner includes a driving portion for driving a plurality of wheels, at least one camera installed on a body of the robot cleaner, the camera for photographing external surroundings, and a controller for photographing an image through a camera for recognition of a connection position where the external recharging device is connected with the robot cleaner and stores the photographed image, and controls the driving portion so that the robot cleaner can move from the external recharging device to a destination when an operation start signal is received in the robot cleaner connected to the external recharging device, and for tracing a path to the connection position of the external recharging device and the robot cleaner during a robot cleaner's return to the external recharging device while comparing a current image currently taken by the camera with a stored image of the connection position of the robot cleaner and the external recharging device. Returning of the robot cleaner is carried out when the robot cleaner, separated from the external recharging device, completes its job or needs a recharging, by using the previously stored image and an image currently taken by the camera. Accordingly, an error in the location process, mainly caused due to external interference signals, is decreased, and errors in tracing a path and connecting to the external recharging device can also be decreased.

Date Jul. 6, 1995An electric fence energizer is operated by an alternating current and has two storage capacitors (C1, C2), which are charged by a charging circuit (7) to a high voltage. The storage capacitors (C1, C2) are discharged through separate primary windings (L1, L2) in a transformer (T) and the secondary winding (L3) of the transformer is connected to the electric fence. The discharging processes are controlled by separate discharging circuits (R1, Ty1; Ty3 and Ty3 respectively), so that for light loads only one of the storage capacitors (C1) is discharged, and for heavy loads also the other one (C2) is discharged starting a short time after the start of the discharging of the first one and during the same discharge cycle. Sense circuits (L2, R8, R9, C3, R10, R11, R12, T4, R13) provide signals PCHL; PPUL) to a microprocessor (7) and they represent the load on the transformer (T). One of the sense circuits (L2, R8, R9, C3) comprises the second primary winding (L2) and is used for measuring light loads. It controls, whether the second storage capacitor C2 is to be charged and can in certain cases control the charge voltage. The second sense circuit (R10, R11, R12, T4, R13) is connected to one terminal of the storage capacitors (C1, C2) and is used for measuring heavy loads. It controls the time for a start of the discharging of the second storage capacitor and can also in certain cases control the charge voltage. In that way the supplied pulses will have a high voltage and a large energy content and a good safety is achieved.

Abstract: The invention relates to a method and an apparatus for making an air gap (L, 1a) over at least one conductor (5, 5a) on a printed circuit board (1), minimizing the losses in the conductor (5, 5a). The well known Sequential Build Up (SBU) technology is used, wherein a carrier (3) with the conductor (5, 5a) is covered by a photosensitive varnish layer (7, 7a). An opening (8, 8a) is made in the varnish layer (7, 7a) above the conductor (5, 5a) by a photographic method. A metal layer (11, 11a) is then fastened to the varnish layer (7, 7a) covering at least said opening 88, 8a) so that an air gap (L, 1a) is formed between the conductor (5, 5a) and the metal layer (11, 11a).

According to an alternative inventive method the carrier (3) also comprises a lower conductor (5b) placed opposite to the conductor (5a) described above on the opposite side of the carrier. In the same way as above the lower carrier (5b) is provided with an air gap (1b). A layer (13) of dielectric material can be fixed to the metal layer (11) to obtain a more rigid construction.

Abstract: The invention relates to a method for electrochemically depositing a catalyst, especially a noble metal, from a precursor layer which is present on a membrane and in which the catalyst material is present in the form of salts that are soluble in the membrane material. According to the method, the membrane is surrounded by an atmosphere containing water vapour during the deposition process, this atmosphere ensuring the stability and ionic conductibility of the membrane. In contrast to methods used up until now, this prevents the soluble catalyst salt from being dissolved out the precursor layer. The method can be carried out in a simple device comprising a sealable vessel which can be advantageously tempered, a holder for receiving a membrane/precursor unit, a gas supply and electrical contacts.
